What else can I help you with?
What chemical they used in Halotron fire extinguisher?
argon and tetrafluoromethane
What is a gas in a fire extinguisher that can put out fire?
The most common 'gas' in a fire extinguisher is carbon dioxide (CO2), but there are others. They include Halon 1211, Halon 1301, FM200, FE-36, Halotron I and a few more.
How do fire extinguishers hold so much carbon dioxide?
Yes, carbon dioxide is found in some types of fire extinguishers. In others, nitrogen gas or compressed air is used. Some expensive types contain other pressurized gases such as Halotron or similar "clean agents" that leave no residue.
What is hcfc 123 chemical fire extinguisher?
HCFC 123 is the raw base material use to produce a halogeanated, safe/effective and environment friendly fire extinguishing chemical agent called "halotron I". It was introduce in early 1990's to replace the "banned" fire extinguishing agents like, Halon 1211 and BCF's, which were found to have a severe ozone depleting potentials. In contrast, hcfc 123 base fire extinguishing agents has a near zero ozone depletion potentials.
Why should not you put fire sprinklers in hospitals especially in operation theatres?
There is no particular exemption for hospitals needing fire sprinklers. In fact, there are many fire hazards in hospitals that increase the need for fire protection. A good design, however, may incorporate additional mechanisms to extend the time for release of water or for using a "dry pre-alert" system in certain areas. Even where there are fixed fire extinguishing systems (CO2, Halotron, etc), sprinklers are typically required "throughout" the facility.
What are the Extinguishing media used on wheel well fire on aircraft?
A wheel well fire is unique because it can be four of the five fire classes:the tires are Class A--flammable solidsthe fluids are Class B--flammable liquidsyou've probably got electrical actuators in there, so you've also got a Class C--electrical--fire on your hands.and the plane has some aluminum, magnesium and maybe titanium components; heat them up enough and you're looking at a Class D--flammable metals--fire.What it WON'T be is a Class K--kitchen flammables--fire.In the air you'll just use your Class ABC built-in suppression system. If you land the thing on fire, they'll use Aqueous Film Forming Foam.
